The water quality of Songhua River (Northeast China) was of concern, especially in l980s and eary 1990s. Many studieshad focused on the source and sink, fate and ecological effects of the main pollutants, heavy metal and toxic organic pollutants.However, only one or several water quality indices were considered separately.The combined effects of multiple indices were sel-dom studied. In this paper, based on the monitoring data, the water quality of Songhua River was analyzed by using factor analysismethod, which comprehensively considered six indices of water quality of each monitoring section. Results showed that the mainpollutants had changed to nitrogenous pollutants originated from nonpoint sources and water quality was variable in different hydro-logical period. Results also presented that the method was comprehensive and efficient in analyzing the dynamics of water quality

松花江的水质一直受到各方的关注,尤其是在80年代末到90年代初。大多数的研究都关注重金属、有机有毒污染物等主要污染物的源、汇、归宿以及生态效应。然而,这些研究通常只考虑一个或几个独立的水质指标,多个指标的联合效应则很少研究。文章在监测数据的基础上,对松花江水质运用因子分析方法进行了研究。利用因子分析方法可以综合地考虑每个监测断面上的各个监测指标在不同水文期的变化。分析结果表明,松花江的主要污染物是来自非点源的氮源污染物,且其水质在不同的水文期是不同的。这一结果也表明,因子分析方法在分析水质动态变化上是综合有效的。
